PHASMIDAE—STICK AND LEAF INSECTS. _Head exserted; prothorax small, not elongate; mesothorax very elongate; the six legs differing but little from one another, the front pair not raptorial, the hind pair not saltatorial. The cerci of the abdomen not jointed, consisting of only one piece; the tarsi five-jointed. Tegmina usually small, or entirely absent, even when the wings are present and ample.
